DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 338,780, dated March 30, 1886.

Application filed July 8, 1885. Serial No. 170,966. (Model) To aZZ whom it may concern.-

Be it known that I, GEORGE W. RICHARD- soN, a citizen of the United States, residing at Plano, in the county of Kendall and State of Illinois, have invented certain new and useful Improvements in Devices for Converting Motion; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My present invention relates to improvements in devices for converting rectilinear into curvilinear motion; and it consists in certain novel features of construction, combination, and arrangement hereinafter described and claimed.

In the drawings, Figure 1 is a plan view with the cap-piece removed. Fig. 2 is a side elevation,partly in section. Fig. 3 is a detail view of the cap-piece, and Fig. 4. shows a modification.

A is the operating-handle, secured to the ring 13 in the ordinary manner.

(3 is a cappiece centrally apertured to fit over a lug, g, projecting upward from the face of the cam D and placed on the ring B, and secured in place by an annular flange of the block d, which latter rests on the lug g and is secured thereto by a screw or bolt, d. The said cap-plate is free to turn about the lug g of the cam-wheel in either direction, to shift the position of the binding-roller,for the purpose hereinafter set forth.

The cap-piece O is provided with two pairs of depending arms, E E, placed opposite each other, as shown. Between the pairs of arms E,I place the double wedges F F, the purpose of which will presently appear.

The cam-wheel D is made of the peculiar shape shown, being elliptical in longitudinal horizontal section and rectangular in crosssection.

A fiat double spring, G, or its equivalent, is secured to the cam-wheel D, and holds the cap-piece Gin position in the operation of the device. The long diameter of the cam-wheel D is about equal to the inner diameter of the ring B, while the short diameter is equal to slightly more than one-half the same. Between the ring B and the cam-wheel D, on the opposite sides of the said wheel, I place the rollers H H. The depending arms E E fit around these rollers and change the position of the same in the operation of the device.

In the drawingsI have shown the cam-wheel D formed on the end of a screw-driver or anger handle; but it can be formed on the end of a drive-shaft or in any other place where it can be used advantageously.

In Fig. 4 I have shown instead. of the double flat spring G two coiled springs, I I, supporting a flat plate, J. Either the double flat spring or the two coiled springs may be used with equally good results.

In operation, the cap-piece O,being turned in one or the other direction, will cause the depending armsE E to carry the rollers in opposite directions toward the ends of the spaces between the ring B and the oanrwheel D, to cause the ring to bind in either direc tion, thereby making the device either right or left handed in its operation, as is manifestly apparent. The rollers will bind between the ring B and the cam-wheel D when the handle is moved in one direction, and will cause the cam-wheel to travel in the same direction as the ring B. As the ring is brought back in the opposite direction,it will slip over the rollers and impart no motion to the camwheel. It will thus be seen that the reciprocating motion of the ring B is converted into the circular motion of the cam-wheel.

The double flat spring G or the flat plate J, acting on the double wedge F, holds the cappiece to any desired position.

Having thus described my invention,whatI claim, and desire to secure by Letters Patent, 1s-

1. The combination, with a ring and a concentric cam-Wheel, of intermediate bindingrollers, and a cap, the latter provided with means to shift the position of said rollers, whereby the parts maybe caused to interlock in either direction, substantially as and for the purposes set forth.

2. The combination, with the cam-wheel having an upwardly-projecting stud, a concentric ring, and intermediate binding-rollers, of a centrally-apertured cap-plate mounted 011 said stud and provided with depending arms arranged in opposite pairs and free to turn around said stud, to shift the position of the rollers in either direction, and interlocking mechanism, substantially as described, to sethe depending pairs of arms E and the double Wedges F, all constructed, arranged, and operating substantially as shown and described.

In testimony whereof I affix my signature in 5 cure the cap-plates in either of its adjusted presence of two witnesses.

positions, as and for the purposes specified.

3. The combination, with the ring B, provided with a suitable handle, of the cam-wheel D, the intermediate locking-rollers H, spring- 10 plate G, and the cap-plate 0, provided with GEORGE W. RICHARDSON.
